HORSESHOE.

Specification of Letters Patent.

Patented. April 10, 1906.

To all whom it may concern.-

Be it known that 1, JOHN E.SHAFFER, a citizen of the United States, residing at Oumberland, in the county of Allegany and State of Maryland, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

My invention relates to improvements in horseshoes; and one object of my invention is the provision of a horseshoe which will permit the ready application of calks of various shapes accordin to the character of service for which the s 0c is intended and which horseshoe will possess merit in point of inexpensiveness and durability and which will be thoroughly efficient and practical in every particular.

To attain the desired. object the invention consists of a horseshoe embodying novel features of construction, combinations, and arrangements of parts for service, substantially as disclosed herein.

Figure 1 represents a plan view looking at the under face of the horseshoe. Fig. 2 represents a sectional view taken on the line 2 2 of Fig. 1. Fig. 3 represents a plan view with a modified construction of calk, and Fig. 4

represents a sectional View taken on the line 4 4 of Fig. 3 and shows the spring-clips on the calk for retaining the calks in position in their seats. Fig. 5 is a sectional view on line 5 5 of Fig. 4 looking downward.

In the drawings the letter A designates the horseshoe proper, the heel and toe portions of which are formed with lugs or projections B, which are provided with dovetailed or tapered sockets or seats O, and in the form of my invention shown in Figs. 1 and 2 fiatfaced calks D are used, formed with tapered. tenons E, which fit snugly in the sockets or seats of the horseshoe.

In the form of my invention shown in Figs. 3 and 4 the calks F are provided with sharpened or flat pointed ends G to enable the calks to enter the ice more readily, the form shown in Figs. 1 and 2 having the flat faces H, which may be used when desired. In all forms of the invention the under side of the calks are provided with shoulders J, which causes a smooth snug fit of the calks in the sockets or seats, and the toe-calk is fitted in an1 lelongated or longer seat than the heelca i.

It is evident that Iprovide a horseshoe particularly adapted for winter use and which possesses every requisite to render it thoroughly efficient, entirely practical, and desirable for the purpose intended.

In the detail view illustrated in Figs. 4 and. 5 I provide the horseshoe with small kerfs or recesses K, in which is adapted to spring the spring-tongue L, formed on the calk, which secures the calk in positionand prevents accidental detachment thereof.

I claim- A horseshoe-having projections at its heel and toe portions, mortised seats in said projections, said toe projection being elongated and having a kerf in the inner vertical wall of the seat therein, calks formed with tapered. tenons adapted to fit in said seats, a springtongue formed on the toe-calk adapted toengage said kerf, and shoulders on said calks adapted to abut against the face of the projections on the shoe. m

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN E. SHAFFER.
